Yes, sorry, I had overlooked that. That’s why I recommended Lufi afterwards.

Oh, over the Internet, not just the local network … then maybe Lufi?

for example this instance: https://upload.disroot.org/

Works well, but not particularly fast with large amounts of data (up to 2GB possible)

KDE-Connect? https://kdeconnect.kde.org/

It works very well for the data exchange between Linux, Android, iOS and Microsoft devices. https://apps.kde.org/kdeconnect/

Of course, it can do a lot more, it’s a bit oversized for just data exchange

I don’t know, I have very good experiences with the Antennas. It (almost always) delivers the expected content. Do you perhaps have a keyword that is also (part of) an instance name?

Then it would have to be added as an excluded word.

The topic of the instance only really plays a role in Mastodon. With Sharkey and most other Fediverse software, there are much better features for structuring the content you are interested in. In Friendica, for example, via the channels and in Sharkey, Misskey and its other forks with the Antennas / News Picker

I don’t know what options there are for admins. lemmy.ml could (temporarily) defederate the instances from which the spam comes. From all Mastodon instances that have a completely free registration, at the moment spam is distributed through the whole fediverse. Lemmy users can block individual accounts, but I don’t think this is possible with a whole instance.

The first paragraph of a post sent from Mastodon (or Akkoma, Misskey etc.) to a Lemmy community will appear in Lemmy as a headline. The character limit is 200 characters, only if it is longer will it be cut off. The post itself is displayed in full. However, only one image is federated, for example.

“But if any M post mentions that L community, the post will get boosted by the community’s M account, so everybody who follows will get a notification.”

That’s not quite right: The Lemmy community boosts the post to the timeline, but not everyone who follows it from Mastodon (or Friendica, Akkoma etc.) receives a notification. The post then only appears in the timeline. You can set whether you want to receive a notification about new posts/boosts from an account

Then there are these two:

https://android.izzysoft.de/repo/apk/io.github.janbar.osmin

https://f-droid.org/packages/com.junjunguo.pocketmaps/

But I have no experience with them

I don’t know the size, but Organic Maps may be rather small

There is also Fediverse software that has integrated ListenBrainz: Sharkey (Misskey-Fork) has the feature “Federated Backgrounds and Music status - You can add a background to your profile as well as a music status via ListenBrainz, show everyone what music you are currently listening too” https://activitypub.software/TransFem-org/Sharkey/-/blob/develop/README.md?ref_type=heads

Yes! Ghost Commander is open source and it’s able to transfer via sftp

I think Diaspora continues to be an active and relevant macro-blogging platform. However, in Fediverse it is now only connected to Friendica and Hubzilla, not to Lemmy and the other software that only use ActivityPub protocol.
